“Flange” tongue adds side protection and guidance vs. standard SV spades.
Overview
WILLELE FSV Series insulated flange spade terminals feature a fork tongue with side flanges that help guide the stud and
provide extra insulation support compared with standard spades. Vinyl sleeves are color-coded by section and the tin-plated copper barrel
ensures low contact resistance and easy crimping.
- Quick connect/disconnect on studs (#6 / #8 / #10).
- Flanged fork for added mechanical protection and alignment.
- Sections: 0.5–1.5 mm² (red), 1.5–2.5 mm² (blue), 4–6 mm² (yellow).
